Terms should be indexed as documentation is written. Use \index{ ... } and
related commands to accomplish this. There should be a space on either side of the
index command, and the command should not be placed anywhere a space should not exist
(such as between a word and a subsequent period or comma).
In order to encourage consistency and ease sweeping changes of indexed terms, there
are macros defined in the indexcommands.tex file. These macros for commonly
used--or complex--index terms should be taken advantage of whenever possible
rather than manually using the \index{ ... } command. Care should be taken
that any new macros added to the file maintain the existing alphabetic ordering
to facilitate a manual look-up of index commands.
